T0111?w/mniitmag/ concern: n

.le it known that I, Anziano J. Dinner, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Springs, of which the following is a specification.

My invention relates to an improvement in springs, and more' particularly to that class of springs used upon vehicles which consists of a number of leaves.

The .object is to construct the leaves in such a manner that a lubricant can be introduced between the leaves to prevent the spring fi'oin squeaking.

lVith the spring that is generally used, it

is necessary to raise or jack the car so that the leaves of the spring can be pried apart for the purpose of introducing a lubricant therebetween. rf he lubricant will prevent squealiing, and will keep the spring from crystallizing. A spring which can be lubricated will ride much smoother and will not rust between the leaves, and will last much longer, doing away with the friction and squeaking between the leaves.

The invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and'pointed out in the claims.

In the accompanying drawings z-Figure l is a perspective view of the invention; and l? ig. 2 is a plan view of the leaves taken from the under or inner side thereof. Fig. 3 is a longitudinal sectional view.

Thev spring consists of a plurality of leaves, A, B, C, D, and E The several leaves are connected together by any suitable means, such as a bolt l, and nut 2. The leaves B, C, D, E are all mounted upon the main leaf A, and leaves B, C, D, and E are all provided with a longitudinal or main orrugation or duct 3. The duct or corrugation 3 'extends preferably 'longitudinally of the leaf from the outer end thereof. Extending radially from the longitudinal corres-ation or duct 3 of each leaf of the *C l leaves B, C, and D are radial duets or corrugations et. These ducts terminate at the outer side edges of t. e leaves, thevdepth G'opes of this patent may be obtained for ve centseach, by addressing the of the ducts 3 and 4f diminishing in size throughout their entire length; that is, the ducts are of greater depth at'their juncture than at their outer ends.-

The provision of grooves or ducts at the outer ends of the several leaves permits the oil or lubricant beingintroduced through the main duct and radial ducts at all times. It makes no difference what lead may be placed upon the spring, the lubricant can always be introduced between the leaves without the necessity of prying the leaves apart, and the lubricant willbe dconducted by the grooves to 'the wearing surfaces of the leaf, and thereby relieve the friction and lrusting of the leaves. Springs which can be lubricated in this manner will be prevented from squeaking and the springs will ride much smoother, as they will be more pliable than they would be if allowed to work and rub together dry.

What I claim as new and desire to secure by Letters Patent is 1. Springs for vehicles comprising two or more leaves of varying lengths superimposed and held together, the protruding ends only rateale-ee Maya, rais..

of said leaves having each a duet stamped therein, the outer end of each of said ducts open at the end of the leaf to receive lubricant without the necessity of separating the leaves.

2. A spring comprising a plurality of leaves having depressions stamped in the ends thereof to produce pockets for a lubri- Commissioner of Patents,
